我继承了一个代码库:)
在src/test/java /下面有一个我需要运行的文件(我需要运行它public static void main(String[] args),而不是其中的@Test方法).
我最接近的是:
mvn -e exec:java -Dexec.mainClass="com.me.packagex.RunFile" -Dexec.classpathScope="test"
但那失败了,似乎是因为RunFile想要使用src/main/java/com/me/packagex /(notice,/ main /,not/test /)下的类.其下的文件与RunFile在同一个包中,即'package com.me.packagex;'.
如果我删除它-Dexec.classpathScope="test"然后它根本找不到RunFile.就好像我需要给它两个范围,但它不接受"测试,编译".
我从(亲爱的离开)继承的人曾经从Eclipse运行它.我需要一种从命令行运行它的方法.
我希望这清楚地解释了.
tyvm,
这很有希望.帕斯卡,我已经试过你的榜样,并且没有为我工作.
虽然现在我看着它 - 它没有找到Demo,而不是找到Dog.

[INFO] An exception occured while executing the Java class. …我正在尝试使用JSONPath(https://github.com/jayway/JsonPath)来搜索字段名称中包含空格的文档:
{
"model": {
"Details": {
"Nospace": "New today",
"Random nonsense": "New today"
}
}
}
我正在使用http://jsonpath.herokuapp.com/上的评估员进行测试
这有效:
$.model.Details[?(@.Nospace== 'New today')]
但这不是:
$.model.Details[?(@.'Random nonsense'== 'New today')]
这样做但缺少过滤器表达式:
$.model.Details['Random nonsense']
因此,似乎可以引用带空格的字段,但我还没有找到如何在过滤器中使用它们.可能吗？我尝试了许多其他没有运气的组合,似乎也没有在网上找到任何关于它的东西.
谢谢.
我发现创建一个AmazonS3Client意味着我的进程即使在什么都不做的时候也会挂起.我正在进行文件上传,但我已将其修改为此.
当我运行以下代码(带有工作凭据)时,它会输出"Simple is finished",但该过程不会退出,直到最终maven:exec告诉我:
